Abstract
The utility model provides a separating funnel capable of measuring temperature, which belongs to the field of chemical laboratory apparatuses. The separating funnel comprises a funnel body, a top plug for sealing the funnel body, a liquid discharge pipe for liquid discharge, and a funnel switch on the liquid discharge pipe, wherein the inner side face of the funnel body is provided with a thermometer; the outer side face of the funnel body is further provided with an exhaust port which is a lug boss. According to the separating funnel capable of measuring temperature provided by the utility model, the mercury thermometer is arranged on the inner side of the funnel body, and when a solution needing to be separated is arranged in the funnel body for standing, the temperature of the solution inside the funnel body can be observed at any time, so that the experimental error is reduced; the exhaust port is arranged in the outer side face of the funnel body, and when a separated solution is incapable of dropping down successfully since negative pressure exists in the funnel body once a top cover is not taken off, the seal plug can be pulled out in time, so that internal pressure and external pressure of the funnel body are the same, and the solution needing to be separated can successfully drop down.
Description
Technical field
The utility model relates to a kind of chemical experiment common experimental instrument, relates in particular to a kind of separatory funnel, but is specifically related to a kind of thermometric separatory funnel.
Background technology
Separatory funnel is chemical experiment a kind of experimental ware commonly used, separatory funnel is mainly used in being separated from each other between the liquid immiscible in the chemical experiment, more common separatory funnel has spherical hopper, pyriform funnel and tubular funnel at present, and its common structure comprises that mainly bucket body, bucket body top are used for the discharging tube of liquid discharge and the funnel switch on the discharging tube for the inlet of charging, the top cover that is used for the sealing inlet, bucket body below.
When using separatory funnel to carry out separatory, concrete steps are as follows: at first the funnel switch cuts out, pour immiscible liquid into from inlet, after treating that liquid is all poured into, manually rock liquid is fully mixed, then separatory funnel is put into funnel stand, make its standing demix, by the control of funnel switch, obtain the solution that separates in regular turn again.
And have at present following drawback in the separatory funnel: when needing in regular turn separation solution behind the standing demix, forget the top cover of opening the sealing inlet sometimes, under the situation that top cover is not opened, open the funnel switch, owing to have negative pressure in the separatory funnel, cause separation solution not drip smoothly; Traditional separatory funnel can't be grasped the temperature of solution in the funnel, also can't recognize the temperature regime of in good time layering, therefore, can't finish experiment accurately.
This shows that prior art awaits further developing and improving.
The utility model content
In order to solve the defective that exists in the prior art, but the utility model proposes a kind of thermometric separatory funnel, this separatory funnel had both solved the problem that the separation solution that exists negative pressure to cause in the separatory funnel is difficult to drip, solve the temperature that directly to learn solution in the separatory funnel again, caused testing the situation that error occurs.
The technical solution of the utility model comprises:
But a kind of thermometric separatory funnel, described separatory funnel comprise the top plug of bucket body, sealing bucket body, the discharging tube that is used for the liquid discharge and the funnel switch on the discharging tube, and the medial surface of described bucket body is provided with thermometer; Described bucket body lateral surface also is provided with exhaust outlet, and described exhaust outlet is a lug boss.
Described temperature is counted mercurial thermometer.
The exit of described exhaust outlet is provided with sealing-plug, and described sealing-plug is oval.
Useful technique effect of the present utility model:
But the utility model proposes a kind of thermometric separatory funnel, be provided with mercurial thermometer in the inboard of bucket body, when the solution of needs separation left standstill in the funnel bucket body, the temperature that can observe solution in the bucket body at any time reduced experimental error; Lateral surface at bucket body is provided with exhaust outlet, under the normal condition, use sealing-plug sealing exhaust outlet, exhaust ports is in sealing state, when forgetting that for the moment taking off top cover makes when existing the negative pressure separation solution not drip smoothly in the bucket body, can in time pull out sealing-plug, make in the bucket body external and internal pressure consistent, make the solution that needs to separate drip smoothly.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further clear complete explanation.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, bucket body 2, top plug 3, discharging tube 4, funnel switch 5, exhaust outlet 6, sealing-plug 7, thermometer.
The specific embodiment
But the utility model proposes a kind of thermometric separatory funnel, concrete more, clear and definite in order to make the technical solution of the utility model, useful technique effect, below in conjunction with specific embodiment the utility model is done further clear, complete explanation.
As shown in Figure 1, but a kind of thermometric separatory funnel, this separatory funnel comprises the top plug 2 of bucket body 1, sealing bucket body, the discharging tube 3 that is used for the liquid discharge and the funnel switch 4 on the discharging tube, the medial surface of bucket body 1 is provided with thermometer 7, inboard at bucket body is provided with mercurial thermometer, when the solution of needs separation left standstill in the funnel bucket body, the temperature that can observe solution in the bucket body at any time reduced experimental error; Bucket body 1 lateral surface also is provided with exhaust outlet 5, and exhaust outlet 5 is a lug boss.
Preferably, thermometer 7 is mercurial thermometer, uses mercurial thermometer simple, intuitive more, convenient temperature of observing solution in the bucket body 1.
Preferably, the exit of exhaust outlet 5 is provided with sealing-plug 6, sealing-plug 6 is oval, is beneficial to and extracts, under the normal condition, use sealing-plug sealing exhaust outlet, exhaust ports is in sealing state, when forgetting for the moment that taking off top cover makes and can in time pull out sealing-plug when existing the negative pressure separation solution not drip smoothly in the bucket body, make in the bucket body external and internal pressure consistent, make the solution that needs to separate drip smoothly.
Need to prove that those skilled in the art can also make such or such variation under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within protection domain of the present utility model.
